To all whom it may 001506151: Be it known that I, THOMAS A. DUNGAN,\ acitizen of the United States, residingV at Chicago, in t-he county ofCook and State of ing in the opposite direction from Fig; 1;

Fig. 4 is a section on the line 4 of Fig. 3; Fig. 5 isa section on theline 5 of Fig. 2; Fig. 6 is afdetailed transverse section through one ofthe cars on the plane indicated by the line 6 in Fig. 2, and Fig. 7 is alongitudinal section on the line 7 of Fig. 6.

Referring to the drawings, A 'is chamber, closed at one end by adoor A1,having in its top pipes A2 by means of which the running horizontal ofthe rails'B an products of distillation may be drawn off to a still.lThe chamber A is preferably built of cement or concrete and it is linedor coated on its interior with an acid resisting compound, such as zincfluates. In this way,

a retort 'suitable for the distillation of Wood is provided at a verylow cost and with the maximum of strength and durability.

B are rails formmg a track upon'which the cars containing the Wood tobeoperated unon can be run into and out of the retort. The rails B arecarried b supports B1 so that they lie-a considerab e distanceA abovet-he bottom of the chamber A, the purpose being to afford a spacebeneath the cars for theheating pipes. `l

The retort 1s heated Iby direct radiation from a flue in the followingmanner: C is a furnace, the smokeipe or exitipe thereof underneat theplane between the supports thereof B1, as shown at Cl in the drawings,and being thlen curved and' brought back at C2 along the side of thechamber, the extreme end of the pipe being turned' upwardly to a stack.The products of combustion are drawn through this 'long flue thuscomposed, in any approved mannen either by a forced draft, asuction-device or' the heated air may rise. slrable to place the. woodon end, that is,

by the use of a tall cliimneypas' may `be desired.

The cars, upon which the wood to be treated is'. placed, `may h-averun-ning gears and frame-work of any desired sort. Each has, however,`areticulated floor made in theV form of a horizontal grate 4consistingof longitudinal rods d and transverseflat bars d* set on edgea'ndthrough-perforations 'in which Ithe rods d pass. There is thus pro-Which the Wood may rest and through whichv It is thought dewith itsgrain running vertically, and this reticulated floor provldes means forsupporting the wood in that position. Under-l neath this reticulatedHoor in each car is a series of transversely extending troughs D,

each of which is made in t-he form of an S or vided in each car areticulated surface lupon reverse curve, the troughs being so arranged lthat one edge-of each overhangs the adjacent edge of the next, in themanner illustrated in Fig. 7, and all the troughs project beyond theside of t-he car on one-side and have their opposite-ends elevated so asto form inclines down which fluid will fiow. There is thus providedunderneaththe fioor i' the cars pass, isa trough E over which the. endsof the car troughs D' project to dis- 1 charge their contentsA therein,a strainer or grating e being provided for the pur ose of catching andretaining any wo chips which may enter with the fluid products. Thetrough E is intersectedA by a partition E1 which comes nearly tothe'bottom of the trough and a pipe E2 extends longitudinally1 ofthetrough on the opposite slde of the partition E1 from that on which theliquid enters. forations through which either air or steam may bei blownthroughl the fluid, in the trough for the purpose of volatihzing as comletely as possible any of the lighter pro'uc'ts contained in the Huid.`The use of air or steam for this purpose, or both in alternation, mayreduce certain chemical effects of a desirab e character, and the pres-'ent apparatus is designed to afford means This' pipe contains a. seriesof-per- W noemer for producingsuch agitation ofthe fluid by directcontact with heated or unheated gas as the case may be. The partitionEl, it will be seen, operates as a dash-plate to prevent the iuid frombeing blown, in its agitation, out of the trough entirely. A valve E3 isprovided through which the treated is of a simple and cheap characterand has the desirable features already pointed out.

I am aware that considerable variation is possible in the details of theconstruction herein shown and described, and I therefore do not intendto-limit myself to such cony struction specifically; my intention being,in

the claims hereinafter set forth to specify all the novelty which isinherent in the construction .illustrated What ll claim as new anddesire to secure by Letters Patent, is-

1. lnv a wood distilling apparatus a car having beneath. its contents aseries of troughs each overhangin the nextv in the series and spacedthere rom whereby the Huid falling from the wood will be caught by thetroughs, while space is provided for the u ward passage of heated air.

2. llii a wood`distilling apparatus a car having beneath its Acontents aseries of troughs each overhanging the next in the series and spacedtherefrom wherebyv the fluid falling from the wood will becaught by thetroughs, while space is provided for the upward passage of heated air,and a reticulated hoor above the troughs adapted -to support thecontents of the car.
